OCR script for greenshot. Creates a text file on the desktop with the OCRed text. Use the External command Plugin to call tesseract_greenshot.bat, with "{0}" as the argument.

Requires greenshot, tesseract, imagemagick, and python to be installed. This could definitely be less cobbled-together, but it works so who cares. Also there might be a real plugin later? Make sure tesseract and python are in PATH environment variable and "Add application directory to your system path" is checked while installing Imagemagick.

Install QPDF, and then edit this batch file with the correct path and create a shortcut to this batch file. Then you can Open With the shortcut file for quick access and it creates an unlocked version of a locked PDF in the same folder as the original.
